This is sub-optimal, and is basically used as a last ditch effort.
There is no actual way to disable UEFI, what actually happens, this
setting enables a compatibility support module that presents a
faux-BIOS to the OS to bridge between the OS and UEFI. So UEFI isn't
actually disabled, you've just added another layer.

What's really needed are logs, to troubleshoot why there's a boot
failure. What's supposed to happen if you're dropped to emergency mode
by dracut, is you get an rdsosreport.txt produced that typically
contains a bunch of information useful for troubleshooting.
